Happy Birthday to My Loose Acquaintance

I wouldn't have known any other way
 Cause we co-exist in a mutually unstated
 So I got ten seconds and they're just for you
 To write on your wall like good people do
 To keep our weak social tie with minimal maintenance
 Happy Birthday to my loose acquaintance
 Look through my photo album, you're not in it
 If I saw you on the street, it would take me a minute
 But I'm such a thoughtful person and I totally care
 That's why there are three exclamation points there
 Colon parenthesis to be more compelling
 All caps so it's just like I'm yelling
 From the top of my heart, just to keep status quo
 Happy Birthday, dear person, who I sorta know
 We both know you're not my real friend
 You're a by-product of a social networking trend
 But you feel just as indifferently about me
 So there's no guilt in our apathetic reciprocity
 So if we don't talk much or at all this year
 Remember I sent you this afterthought cheer
 To keep our minor affinity with minimal maintenance
 Happy Birthday to my loose acquaintance
